You actually CAN protect against that, I think:
3ware won't ever be on pci 0000:00,
'internal' disks won't ever be on pci 0000:0[123456789]

Fortunately even after changing the mainboard internal controllers are
still internal.
Should be ok unless you add a third disk controller to the mix (I
would make an experiment with USB thumbdrive
just in case)

LVM could help in mapping, too (but I think you want to setup storage
from scratch, without existing LVM)

PS:If you get it ready in FAI I would really like to see the configs,
as I'm replying
on the basis of 'generic' thinking, which may not fully map (pun
intended) to FAI.
